Well update - Kenya

Tullow Oil plc (Tullow) announces that the Emesek-1 exploration well in Block 13T in the North Lokichar basin, Northern Kenya, has reached a total depth of 3,000 metres without encountering commercial hydrocarbons.

The Emesek-1 well was drilled by the PR Marriott 46 rig. The well will now be plugged and abandoned. Following completion of operations, the rig will move to the South Lokichar basin to drill the Etom-2 well which is expected to spud in late November.

Tullow operates Block 13T with 50% equity and is partnered by Africa Oil Corporation, also with 50%.

ANGUS MCCOSS, EXPLORATION DIRECTOR, TULLOW OIL PLC, COMMENTED TODAY:

“The Emesek-1 well was the first well to be drilled in the North Lokichar basin. While this wildcat well did not find commercial hydrocarbons, it provides valuable data as we assess the wider prospectivity of this basin.”
